For reference, here are the key grafs from the (revised) Politico story (my emphasis; note the sourcing):

The roots of the partisan standoff that led to the postponement of the bipartisan White House summit scheduled for Thursday date back to January, when President Barack Obama dominated a GOP meeting in Baltimore and delivered a humiliating rebuke to House Republicans.

The one-sided televised presidential lecture, which many Republicans decried as a political ambush — Obama’s staff wanted the event to be broadcast and GOP aides agreed reluctantly at the last minute — has left a lingering distrust of Obama invitations and a wariness about accommodating every scheduling request emanating from the West Wing, aides tell POLITICO.

“He has a ways to go to rebuild the trust,” said a top Republican Hill staffer “The Baltimore thing was unbelievable.”

Many Republicans; aides; top staffer. They might as well have said “Republican PR firm” — those quotes sound focus-group tested to me.

And while Rachel is being polite, I don’t have to be. When Politico, in its own voice, writes: “The one-sided televised presidential lecture … has left a lingering distrust of Obama invitations” — well, it’s asserting for itself that the demonstrably false Republican spin-leaks are true. And they’re not.

Looks like the deeds of a right-wing water-carrier to me. But hey, that’s me, just watching the deeds. (By the way, for accuracy of attribution, the author of that phony story is Glenn Thrush. Someone to notice the next time you read his stuff. He’s the one with the squeeky-wet shoes.)

Olbermann did a terrific job in his Special Comment on Real News. Maddow has continued to carry the ball on that one all week, and this segment is one of her best.
